Fluctuation-induced spin nematic order in magnetic charge-ice
A. Hemmatzade, K. Essafi, M. Taillefumier +3
Disorder in materials may be used to tune their functionalities, but much more strikingly, its presence can entail entirely new behavior. This happens in charge-ice where structura…
First order phase transitions in polymerized phantom membranes
K. Essafi, J. -P. Kownacki, D. Mouhanna
The crumpled-to-flat phase transition that occurs in D-dimensional polymerized phantom membranes embedded in a d-dimensional space is investigated nonperturbatively using a field e…
Nonperturbative renormalization group approach to Lifshitz critical behaviour
K. Essafi, J. -P. Kownacki, D. Mouhanna
The behaviour of a d-dimensional vectorial N=3 model at a m-axial Lifshitz critical point is investigated by means of a nonperturbative renormalization group approach that is free…
Crumpled-to-tubule transition in anisotropic polymerized membranes: beyond epsilon-expansion
K. Essafi, J. -P. Kownacki, D. Mouhanna
Anisotropic D-dimensional polymerized phantom membranes are investigated within a nonperturbative renormalization group (NPRG) framework. One focuses on the transition between a hi…
